cl E. POST ADJUSTABLE GAUGE Filed NOV. 1, 1927 l NVENTOR 61E Post ATTORNEY Patented Apr. 28, 1931 TED TATES CHARLES E. ros'r, or LOS ANGELES, CALIFORNIA ADJUSTABLE Gauss.

Application filed November This invention relates to the building art, and is more particularly concerned with an adjustable gauge for obtaining relatively angled measurements such as inside measurements, and including angles, such for example, as are necessary in stair work, shelving and other forms of work requiring inside measurements and angles for cutting to fit.

An object of the invention is the provision of a durable gauge of simple construction adjustable to a relatively wide range of work, including inside measurements involving variably angled sides. These features as well as other structural features and advantages are more fully defined in the following detailed specification, when read in connection with the accompanying drawings forming part thereof, and in which:

Figure 1 is a plan view of the gauge unextended and with the side gauging arms at the perpendicular, the extension of the longitudinal gauge bars and the angled adjustment of the side angle bars or arms being shown in dotted lines.

Figure 2 is a perspective detail of the gauge shown in full lines in Figure 1.

Figure 3 is a vertical section on an enlarged scale through the ad usting clamp taken on I the line 33 of Figure 1.

Figure 4 is a sectional view on an enlarged scale taken on the line 4.4.- of Figure 1.

Figure 5 is a sectional view on a similarly enlarged scale through a guide yoke taken on the line 55 of Figure 1.

In carrying out the invention, provision is made for a sectional bar, which may be termed a length bar, comprising overlapping bar sections 1 and 2, preferably of flat steel, connected together for longitudinal extension and contraction. To this end, the inner bar 1, as viewed in Figure 2, is provided at one end with a yoke 3 to which it may be affixed by suitable means, such as a screw 1. The yoke 3 embraces also the outer bar section 2, which at its opposite end is provided with a similar yoke 10, embracing also the inner bar 1 in a manner later to be described. The end of the inner bar 1, opposite the yoke 3, extends through and beyond the yoke 10, and is provided with an angularly ofiset end5 to 1, 1927. Serial No. 230,278.

whichone end of a side anglearm or bar 6 is jpivotally secured. I Preferably, the side angle arm 6 is provided adjacent to its end witha threaded stud 7, which extends freely through a pivot hole formed in theoffset end 5, and isengaged by a clamping arm 9, haw ing a threaded bore therein into which the projecting end of the stud 7 threads. A suitablewasherB is, interposed between the face of the offset ,andthe clamping arm 9. Turning the clampingarm obviously draws the faceof the bar. 6 against the end 5 and clamps it thereto. H j

Y The yokes 3 and 10, as previously stated, join the sections 1 and 2 of the extensible .lengthzbar and guide themin parallel relation The yoke 10 carries means, in the form of-a threaded stud .11 with a suitable operating head, by means of which the barsections 1 and 2 may be clamped together in their longitudinally adjusted positions. The stud 11 is threaded through alined apertures in the yoke 10 and outer bar 2 to impinge against the inner barl and to clamp it against the opposite side of the enclosing yoke.

I Theopposite end of the outer bar section 2 is provided, similarly to the inner section 1,

which theendof alcomplemental side angle bar 13 is pivotally mounted by means of its stud 14 projectingfreelythrough a pivot apwith an angularly inclined end12, upon erture in the end 12, and engaged at its outer projectingend by a similar clamping arm 15, a. washer 16, being interposed between the clamping'arm and the adjacent face ofthe end12. Y V.

The outwardly and. upwardly inclined ends 5 and 12 of the length bar are of decided .advantage in enabling the side angle arms 6 and 13 tofit within and engage with their edges the innerfaces of workto be gauged, where the angles of these faces to the length bar is other than right angular. The gauge, being formed of flat steel bars, is practically indestructible, and will withstand considerable abuse. The side arms, when the gauge is not in use, may be folded down to lie over and parallel with the length bar, so that when the latter is shortened toits minimum length, and the side'arms collapsed thereover, the

gauge occupies a minimum of space commensurate with its range of adjustment. Obviously, this range is substantial since the extended length of the bar sections 1 and 2 is practically double that of their collapsed length, and the side arms 6 and 13 being of a length adequate to cover a substantial area not interfering with the collapsing of these arms over the length bar. The arms 5 and 12-at the opposite ends of the length bar which form permanent extensions thereof are inclined outwardly in divergent relation to said bar and are advantageous When their respective side angle bars 6 and 13 are to be used to measure, for example, for the side angularity of the sides of'a shelf or stair treadhaving sides divergent'outwardly toward their inner longitudinal edges froma longitudinal outer edge of less length. The inclined arms or ends 5 and 12 of the length bar, under these conditions, can by adjustment of the vertical length of thelength bar sections 12, be inserted inwardly beyond the outer longitudinal edge and the side angle arms 6 and 13 can be adjusted to co'ntact'the sides of the opening and gauge the side "angularly oif'the stair tread or-s'helf. WVere these arms '6 and 13 pivoted to the arms of the length bar l' 2 in its linear dimension, this would not be possible.

Vhile the form of the invention illustrated and described herein is a preferable one, it is intended as illustrative of the invention rather than restrictive, and it is contemplated that various structural changes and adaptations may be made in consonance with the spirit of the invention and the scope of the appended claim;

What I claim and desire to secure by Letters Patent is: a r

A gauge comprising a length bar composed of overlapping rectilinear sections yoked together for relative longitudinal extension and contraction and-provided with means for fixing them in longitudinallyadjusted positions,

said sections at their outer extremities havin rigid extensions inclining outwardly and upwardly in divergent relationrelatively to one another, side angle bars,threaded studs pivotally connecting one endof the side bars to the outer ends of said divergent extensions, said bars being adjustableon said pivots to define with their edges sideangularrelations to said length b'anand clamping armsthreadedron said studs for clampingsaid side-angle bars to said extensions in such angrrlarl adjusted relations. 3 CHARLES POST.
